Featured Puzzle: Hitori #3 – Doppelgängers
The masquerade ball is in full swing, but you realize that shapeshifting monsters have mixed into the crowd. Fortunately, they don’t fully grasp logical instructions. Many of your guests wore the same costume, and you ask them to stand in a grid where nobody in any row or column is dressed the same. Any duplicates must be doppelgängers!
How to Solve Hitori Puzzles
Find and shade all duplicate numbers in rows and columns, leaving only unique digits. No shaded cell may be adjacent to another, and unshaded cells must form a contiguous area.
